Peel off the lead you added there.

Do you still plan on publishing a book? I too would be very interested in reading it.

Thanks

I'm not the one writing a book, it's "travlerajm".

I'm pretty sure a wristband isn't going to affect the swingweight of your racquet.

[newyorkstadium]

But doesn't a wristband add mass to your arm and slow down swing-speed, thus making it harder to yield a high swingweight racket?

Travlerajm, I don't have any lead tape on the racket. I have measured it and it is already at my preference of 20.55.

Will I have to make the racket less headlight if I wear wristbands? From what I've read, a more head-heavy racket is less comfortable, has less spin and is worse for volleys.

This question of wristbands increasing SW is interesting, especially in hot weather as they can absorb a lot of weight in sweat.

In another thread I noted that while SW calculators such as TW's show virtually no increase in SW when adding mass towards the butt cap I've felt a loss in maneuverability and RHS speed when adding mass there. I've also noticed an increase in RHS when reducing weight near the butt cap and under the grip.

Since a consistent stroke means NOT usng the wrist alone and instead using the shoulders and core to swing it stands to reason that an increase in mass anywhere on the frame and even the wrist will reduce RHS. The effect will still be greater towards 12 but still of significance near the butt and even the wrist.

In other words, these SW calculations (eg TW's) using a point on the handle as a reference point are wrong imo. They don't match real-world experience and they don't make sense based on a proper swing as opposed to a wristy-swing.

My racket was measured by RDC machine and is naturally at my optimal mgr/i. I just wonder if a wristband has negative effects. I think wristbands slow down swingspeed, and I would have to make my racket more head heavy to achieve optimal mgr/i.

Travlerajm, do you agree that for unleaded racket, wristbands will have a negative impact on performance?

From what I've read, a more head-heavy racket is less comfortable, has less spin and is worse for volleys.

The MgR/I value determines how fast your racquet pivots about the wrist axis during the first part of your swing. If you wear a wrist band, it slows down the rate at which your arm rotates forward during the first part of the forward swing, such that the relative rate of the racquet becomes noticeably faster compared to that of the hand, which will noticeably affect your timing provided you are using a relaxed wrist and not applying a significant couple from the wrist. However, the difference in arm speed is unlikely to have a noticeable effect on the absolute swingspeed.

For the record, I am neither pro wristband nor against. However, I recommend that once you find a racquet and optimize its balance for your swing, it is essential to be cognizant that a wristband can affect your timing, and it's best to stick with one way or the other.

someone help me here. I do not get whether this discussion about wristband vs. no-wristband is serious or just in jest??

The wristband talk is serious, and the data in the other thread referenced in the OP backs it up... the discussion of g at different latitudes, not so serious.

could you kindly quote the exact post from those threads that provides any scientific data backing up your wristband adjustment theory?

i mean other than your own made up claim "a 0.2 'correction factor' has been added to the MgR/I value for all players found to be wearing wrist bands during matches in their peak years (or when the measurement was taken). The correction factor is needed to account for the extra weight of the band, determined to be 0.2 based on the effect of wearing a standard size wrist band on optimum MgR/I value when tuning my own racquets against a wall."

i mean this is beyond silly.....

Amazingly enough -- they are serious.

Although I think the entire thread should be viewed in jest.

Maybe people should -- I don't know -- get out on the court and hit some balls.

That's how you get better.

This is just crazy - crazy sh!t.

Okay thanks. I always thought I would have to go lower swingweight if I wore wristbands. Clearly it was all in my head.

I will optimise my mgr/i with wristbands and without, then see which setup I prefer.

What if you wore the wristband slightly further up the arm so that it wasn't affecting the pivot point of the wrist?

I was thinking the same thing. I wear a wristband on the forearm.

Travlerajm, are you still planning on publishing a book about your findings?

I know it's a bit off topic, but I can't see the point of a sweatband. I never wear one. It's only going to stop sweat rolling down your arm onto your hand, but the hand itself sweats. The sweatband can't stop that. I feel it heats up the area and you end up sweating more. Why not just use a towel, then you can dry the whole area?

[newyorkstadium]

Like a lot of people, I sweat in between points. As you can't reach for the towel in between points, I need an alternative. Otherwise I get sweat in my eyes and my vision is impaired.

Why can't you have a towel behind the baseline and use it between points? If it's sweat coming into your eyes then why not use a headband?

[newyorkstadium]

Good point. I think headbands look silly, though

[newyorkstadium]

Travlerajm, can I tune my racket on court by rallying with a partner.

Thanks

Hi travlerajm,

I have one question, whats the formula to adjust a one backhand, its the same MrR/I= 21?
